4.7 TRANSFORMATIONS
4.7.1 Transform
Use Transform to horizontally and vertically move, scale,
and skew outlines. For scaling and skewing, you can set the
transformation origin to baseline, x-height, cap height, half
x-height and half cap-height. Skew without optical correction
by activating the Slant option, or with optical correction using
the Cursify option. Cursify requires correctly set vertical and
horizontal stems in the Masters tab of File > Font Info.
4.7.2 Background
Use the slider in the Background tab to interpolate between
front and background paths. The paths need to be compatible.
This is useful if you want to experiment with a feature of
a glyph, e.g., the length of a stroke. You can quickly copy a
path into the background by choosing Layers > Selection to
Background (Cmd-K).
4.7.3 Metrics
In the Metrics tab, you can set the width and sidebearings of
all selected letters at once. With the Relative option, the values
will be added or subtracted.
4.8 THIRD-PARTY FILTERS
You can extend the functionality of Glyphs by installing
additional filters. You can do so by double-clicking the file
carrying the ‘.glyphsfilter’ sux. Glyphs will automatically
put it in the correct folder, but needs to be restarted once
afterwards. The filter will then show up in the Filter menu.
You can uninstall a filter by opening the Application
Support folder for Glyphs and moving the respective files out
of the folder called ‘Plugins’. A quick way to navigate to that
folder is Script > Open Scripts Folder. The ‘Plugins’ folder is
located on the same level as the ‘Scripts’ folder.
